<h2>Description</h2>
deen is a set of assembly-optimised denoisers.<br>
<p><strong>use</strong> :<br>
  deen(string &quot;name&quot;, int &quot;mode&quot;, int &quot;thrY&quot;, int &quot;thrUV&quot;,
  float &quot;ti&quot;)</p>
<p><strong>name</strong> :<br>
  you choose the denoising method here (c3d, a3d, a2d, m2d).<br>
  default : &quot;c3d&quot;</p>
<p><strong>mode</strong> :<br>
  with &quot;c3d&quot;, it's the weight matrix.<br>
  - 0 &lt;121&gt; matrix (default)<br>
  - 1 &lt;111&gt; matrix (softer)<br>
  with other methods, it's the spatial raduis.<br>
  default : 0</p>
<p><strong>thrY</strong>, <b>thr</b><strong>UV</strong> :<br>
  luma (Y) and chroma (UV) thresholds.<br>
  higher values blend more. <br>
  default : 10,12</p>
<p><strong>ti</strong> :<br>
  temporal influence.<br>
  maximal mean local temporal difference<br>
  allowed to enable 3d filtering.<br>
  default is 3</p>
<p><strong>methods :</strong><br>
  several methods are implemented :</p>
<p>- this release is a preview for the &quot;c3d&quot; mode.<br>
  it's fully functionnal, and i results are very<br>
  very close to vlad's Convolution3D filter.</p>
<p>- you can test &quot;a3d&quot;&amp;&quot;a2d&quot; mode. it's my own<br>
  2d/3d denoising algo implemention. it's in beta-stage.<br>
  you can try deen(&quot;a3d&quot;,1,10,12) as an alternative <br>
  to c3d with &lt;111&gt; matrix or deen(&quot;a2d&quot;,2,10,12) <br>
  for 5x5 spatial filtering.</p>
<p>- &quot;m2d&quot; is in alpha-stage.<br>
  but you can take a look at deen(&quot;m2d&quot;,1,10,12)<br>
  (mmxed 2d msoften2 / 21x21 emulation )</p><br>
